To all whom it may concern:

Be it known that we, RAYMOND \YAL- TER and lVAL'rnn M. DAKE, citizens of the United States, residing, respectively, at New York city, in the county of New Yorkand State of New York,and at Franklin, Venango County, State of Pennsylvanimfhave invented certain new and useful Improvements inApparatus for Use in the Construction of Framework Supports for Conveyers, of which the following. is a specificationi 1 Qur invention relates to apparatus for ilse in the construction of conveyers and while it is intended that it be usedin the construction of conveyers for handlingall kinds ofmaterial, it is particularly adapted for usenn construction of conveyersv used in mining and transporting coal;

An object of our invention is to provide an improved framework for a conveyer.

Another object of our invention is toprovide-an improved support for a conveyer. Yet another object of our invention is to provide an improved framework orsupport for a conveyer, which is open at one side to facilitate removal and replacement of. the.

returnchain flights or belt. I 7

A' still further object of our invention is to provide a framework or support, for a conveyer, which will be easily manufactured, light in weight and of great strength.

A still further objec-t'of our invention is to provide an improved support, for a con- H veyer, which will make it more readily extensible inasmuch as its open 'side'oryend permits insertion or removalof parts ofthe conveyer without cutting, breaking ortaking apart the lower conveying element whether chains, flight orbelt. f p

In constructing portable extensible conveyers, such as those commercially known as the Claghorne type, it is customary to build a supporting members on both sides of the movingconveying members. These vertical members are joined by horizontal members at top and bottom, these horizontal .inembersforming the-supports for the upper and low'ermem bers respectively of the moving conveying element.

and is'unsatisfactory in operation;

framework having. vertical 1 ap endedjclaims contained within and moving in theirec tangular frameworkuof horizontal and 'vertical supports, breaks or becomes worn,

much-time is lost in making repairs because it is extremely diflicult' to work in the restricted space, and thecontinuous broken worn element can be removed, for a new one 'JAlsowhen it'is desired tofeirtend ain tensiblc conveyer' of thensual type'by the given point, the same disadvantage appears andit becomes necessary to cut, break or open the upper and lower conveying elements. Another section of framework is are very expensive. .It is to overcome their shapethat it has an open side, and is gen lerally formed of. metal bent into U-shape. Vilhen our support 1s used, the lower 'conveying element can be lifted out of its guides,

inserted, mny by passingit longitndinally through frame after frame the entire length ,of theconveyeni .66 insertion of additional unitfiamesatany then inserted and sections ofconveyingele I "m'ents inserted and reconnected ready for use. I

" Theseoperations consume much time and drawn out to one side, repaired and replaced 1 with small delay as compared with similar work;using present supports. a

. Inlike mannerif desiredto insert or Ire move interior sections ofa conveyeruising our improved supports, a section can be takenout or one can beinserted without disconnecting or cutting the lowerconveying element, orwithout being obliged to remove it longitudinallythrough the entire conveyer supports. Moreover, our improved" support is sturdy, simple and economicallymanufac- 'tured. H v y With these and other objects infview which may be incidentlto our improvements,

,the invention consists in the-parts con1-' binationsto be hereinafter set forth and claimed, j with the understanding that the 'i s eve'ral. necessaryfelements comprising our invention, may be" varied in construction, I p '.propo r tio11s and arrangement, withoutde- Thistype of framework is costly to bnild;

The lower conveyor element is adafptecfll to run in guides 7havii1-g upstandi-hg sides 8 The upstanding sides -8 are ioillyjof suifioieht height-to prevent lateral displacement of the conveyer element 2. To join the section-s of the guides, t-he're'a're provided splicing members '9 -winch, inthe present; instance, comprise metal plates wh'iohfiit' againstthe upstanding wells 8 of the guides 7, and across the bottom thereof, 1&1 whieh si-er scehedhy ineaiis suitable belts or rivets 11.; I f f To support the path ear .7 the u per jcehvejer element .1, fandlthe guides 7 carryihg the later Genre-yer element 2, we have shown eonveyer supports 12 which, Iinthe piiesent 'ii'i'sta n'ce, we ztoi i'n of I-beahi', as eons stloilg tiidfofrhs and bottom I-y 'ieasoh or the iflaiigfels. 7 e piilse's fan upper l io'ifl"zentelly "exten'dl-ilglg 13;, am lower 'ho-rfz o'ntally extend n a The upper and lower horizontellv exieh farms ebnheetedfby e Iihk T15, winch is tamed by bendihg the uetu're f theI-loeem.

The upper support '13is provided"with apertures 16"in the flanges of the upper surface of the I-bea-fm. The lower support 14 is means of suitable rivets or bolts 18 to the top 1 surface of the upper horizontal arm 13 by i'p'a-ssing suitable bolts or rivets through the holes 16. The guides 7 are likewise fastened by'ihe'ans of suitable bolts or rivets 19, which pass through the holes 17 in the upper surface'of the lower horizontal arni 1 1 of the support. I r v V In operation, our 'ty 3e of support for the e meyee perinits upper and lower sections of the conveyer to be readily i einoved for repair or replacement by reason o-f'the fact that it is possible-to lift sections oi. the eonveyer bodily out at the lower guides; This feature is or great'advantage,elsojih length eni'ng or shortening the conveyer, where seotions of the upper and lower: elemehts can be eesily and quickly removed. [By reason of the fact that the suppe'rts for the boilveye r allow read access to and removal of conveyer elements, the labor and expense of repeirihg replacement a a changing the length of portable conveyersisgreatlymint' inized.
